HANGER FOR TR'OLLEY-WIR'ES.

SPECIFICATION forming part of Letters Patent No. 746,437, dated December8, 1903.

Application filed'July 1,, 1903. Serial No. 163,858. (No model.)

To all whom it may concern.-

Be it known that I, JUAN ANTIGA, a citizen of the Republic of Mexico,residing at Mexico.

city, Mexico, have invented a certain new and useful Improvement inHangers for Trolley- Wires, of which the following is a specification.

My invention relates to a new and useful improvement in hangers fortrolley-wires, and has for its object to provide an improved hangerwhich is so constructed that if the trolley-wire is broken at any pointthe hanger will operate to cut offthe current from the broken section ofthe wire at both ends of the section, thus preventing any damage beingdone by the grounding of the broken wires.

With these ends'in view this invention consists in the details ofconstruction and combination of elements hereinafter set forth and thenspecifically designated by the claim.

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same, the constructionand operation will now be described in detail, referring to theaccompanying drawings, forming a part of this specification, in which tFigure 1 represents a side elevation of my improved hangerin its normalposition; Fig. 2, a similar view to Fig. 1, showing the hanger in theposition it would assume when a sec tion of wire upon one side of thehanger had become broken; Fig. 3, an under side plan view of the meetingends of the movable members of the hanger.

It is a well-known fact that when a trolleywire is broken from any causewhatsoever and the broken wire descends toward the ground great damageis generally caused before the main station can be notified and thecurrent cut off, and while this is more especially true of trolley-wiresit is also true of all wires over which a current of high potentialpasses in which the ground is used for the return of the current. Withmyimproved hanger I obviate this disadvantage by automatically cuttingoff the current from the broken wire instantly and before the wirereaches the ground.

My hanger may be supported or suspended in any manner desired from across-wire A or any other suitable support.

the switch members.

B is the body of the hanger and is the portionwhich is connecteddirectly to the support A. This body B may be made of any suitableinsulating material desired. Secured upon each side of the body B arethe rightangle brackets C, the vertical members of which are secured tothe body, the horizontal members extending outward in oppositedirections from each side of the body.

D represents the movable or switch members of the hanger, and each ofthese members is in the form of an inverted T. The vertical member ofeachswitehmemberlD is pivoted to one of the horizontal members of thebracket 0 at a point inside of the ends of the horizontal members of thebrackets, and when the hanger is connected and in its normal positionthe horizontal portions of the switch members lie'in line with the wire,the trolley-wire E being connected to the outer end of each horizontalportion of The inner end of the horizontal portion of one switch memberis bifurcated, as indicated at D, and the inner end of the horizontalportion of the other switch member is in the form of a knife or tongue Dadapted to enter the bifurcated portion of the other switch member whenthe parts are in. their normal position.

F represents springs interposed between the outer ends of the horizontalmembers of the brackets C and the outer ends of the horizontal portionsof the switch members.

When the trolley-wires E are drawn taut from one hanger to the otheralong the line, the tension of the wire Will act so as to keep thehorizontal portions of the switch members in alinement, and thereforethese two movable portions of the hanger will be electrically connectedwith one another by means of the knife-switch in the center; but shouldone of the sections of wire between the hangers become broken thetension of the wire will be removed, and the spring B will then act uponone side, so as to throw the outer'endof the horizontal portion of thatswitch member downward and rock that switch member uponits pivot, so asto bring the inner ends of the switch members out of electricalconnection with one another and therefore out 06 the current from thebroken wire, as shown in Fig. 2.

Of course I do not wish to be limited to the exact construction hereshown, as difierent modifications of this principle could be madewithout departing from the spirit of the invention.

Having thus fully described my invention, What I claim as new and usefulis- In a hanger for electric wires, an insulated body, horizontalbrackets extending outward from each side of the body, two switchmembers, each in the form of an inverted T, the vertical portion of eachswitch member being pivoted at its upper end to one of the bracketsinside of the outer end of the same, trolleywires connected to theextreme outer ends of the horizontal portions of the switch members, theinner end of the horizontal scribing witnesses.
